Abstract
The utility model provides a yoke series-wound reactor, consisting of an upper coil arranged on an upper iron core, a lower coil arranged on a lower iron core, an upper iron yoke assembly and a lower iron yoke assembly which are connected into a whole by screw rods and channel steel, wherein the upper iron yoke assembly and the lower iron yoke assembly are an upper iron yoke, a lower iron yoke and a common iron yoke, the three iron yokes of the upper iron yoke and the lower iron yoke as well as the common iron yoke form two sealed magnetic circuits through two groups of the upper iron yoke and the lower iron yoke, and the common iron yoke does not have magnetic flux when the two sealed magnetic circuits are used. The yoke series-wound reactor is combined by two single series-wound iron core reactors and has the volume only 80 percent of the two reactors. If the two reactors are used, the common iron yoke does not have the magnetic flux or consumption. Compared with the two independent reactors, the iron core consumption of two yokes is saved, the reactor stray loss is 50 percent, the capacity of the reactor is twice of that when only one of the two reactors is used, and one reactor can be operated by grouping and according to the capacity. The yoke series-wound reactor has compact structure, saves energy and materials, is economical and practical, has strong practicability and small volume, can be put directly in a switch cabinet to use, and can meet the requirement of installation and maintenance for users.
Description
Technical field
The utility model relates to a kind of reactive power compensator that is used for electric power system, the little conjugation-type series reactor that can meet consumers' demand of particularly a kind of volume.
Background technology
Conventional habitual reactive power compensator is used series reactor more, mainly contains oil immersed type, dry type iron core formula, dry-type hollow series formula, and such reactor volume is all bigger.
Now adopted the reactive power compensator of many groups automatic switching Shunt Capacitor Unit more at large, to adapt to the unequally loaded needs.Because local compensation and dispersion compensation, littler when the former single group of Capacity Ratio of every group of shunt capacitor, series reactor is used, the user needs reactor is directly placed in the switch cubicle, so that install, operation, safeguard.Though at present the low capacity series reactor volume of general structure is little, volume does not successively decrease by certain linear rule with capacity, and therefore still can't to satisfy the user little to volume for existing series reactor, the requirements that make many group reactors can put into switch cubicle simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of conjugation-type series reactor is provided, and volume is little, in light weight, makes full use of the switch cubicle useful space, can directly put into switch cubicle with organizing series reactor more, user friendly operation, maintenance, and energy-conservation, material-saving, low noise.
The technical scheme in the invention for solving the above technical problem is: the conjugation-type series reactor, by the upper and lower coil that is installed in tape insulation on the upper and lower iron core and constituting with the integral body that screw rod, upper, middle and lower channel-section steel connect into by upper and lower iron yoke assembly, described upper and lower iron yoke assembly is a upper yoke, a shared iron yoke, a lower yoke, described upper and lower iron yoke, shared iron yoke, the three-iron yoke constitutes the magnetic circuit of two sealings through two groups of upper and lower iron cores, upper and lower coils from parallel connection of coils, when using two closed magnetic paths simultaneously, no magnetic flux in the described shared iron yoke.
Compared with prior art, advantage of the present utility model is: a conjugation-type series reactor, being essentially two single series connection iron core reactors combines, but its volume only is 80% of two series connection iron core reactor volumes, particularly saved the space of switch cubicle short transverse greatly, volume is little, in light weight, fuel-efficient, province's steel.If during upper and lower two groups of reactor commons, no magnetic flux is promptly lossless in the shared iron yoke, compares with two independent reactors, has saved the core loss of two yokes.Also saving 50% reactor stray loss nearly simultaneously, is energy-saving therefore, and the little switch cubicle of directly putting into of volume uses, and satisfies the needs of user installation, maintenance.In addition, when using upper and lower two closed magnetic paths simultaneously, the reactor capacity is the twice when using one of them magnetic circuit separately, so just can reach can the divide into groups purpose of branch capacity of a reactor, its compact conformation, economical and practical, practical.
